Abstract:

 In northern Morocco, goats’ diet is based on forest pastures characterized by low availability of fodder supply. Substitution of conventional feed resources for livestock with widely available agricultural residues could be used in ruminant feed. However, this substitution requires prior knowledge of their nutrient intake. This work aims to evaluate the chemical composition of some of these agricultural residues available in the region. Samples of residues from red fruits (strawberries and raspberries) and legumes (faba beans, chickpeas, and beans) were collected. The studied parameters were dry matter, mineral matter, fibers (NDF “neutral detergent fiber”, ADF “acid detergent fiber” and ADL “lignin”) and secondary compounds (total phenols and condensed tannins). The results showed that all the parameters differed significantly according to the studied by-products (P<0.01). Strawberry residues had the highest water content compared to other by-products (67.5%). Mineral matter was lower in chickpea residues (6.6% DM) and higher in raspberry and bean by-products (10.5 and 9.4 % DM, respectively). The lowest fiber content (NDF, ADF and ADL) was found in raspberry residue (47.5, 29.6, 11.4 %DM, respectively). Strawberry residues had the highest concentration of secondary compounds (25.5 and 4.3%DM of total phenols and condensed tannins, respectively), while the lowest levels were observed in bean by-products (10.2 and 1.1%DM of total phenols and condensed tannins, respectively). In conclusion, the use of these agricultural residues seems to be a solution to diversify livestock feed and reduce feed costs.
